Accessible Circuit Sticks

thingiverse

This replicates the function of the Steve Spangler "Energy Stick," creating a simple circuit that makes a beeping sound when both ends are held by someone. The idea is to build a platform that enables a blind or visually impaired student to assemble a basic circuit easily. The body was cut from 1/4-inch birch, and a schematic made from thick cardstock or poster board was also created. First, the perimeter of the body is cut. Then, with the wood still in the laser cutter, the schematic is glued to the surface of the body, using the rectangle around it as a guide. Next, the holes of the body are laser-cut. This results in a board featuring a raised schematic and holes at the node points. Conductak is placed into the holes, and component legs can be inserted and removed just like on a large breadboard. More details will follow soon.
